This is part of problem 4. What is the saturation current IS for Diode 1? Choose the closest answer.  Hint: pick a well defined current-voltage point. 

Part 3 . You are given the following diode circuit. Please answer the following questions and show your work on the scratch paper.  R2 = 2kohms, R1 = 1kohms Match with closest answer, you may reuse numbers.

Part 1  Use the ideal Op Amp circuit below to answer the following questions. Make sure to show your work on your scratch paper, including the answer with units.  Po is the power to the load, Pi is the power supplied by source Vs. Vs = 2V, Ri = 1kohms, Rf = 4kohms, RL = 2kohms Match with closest answer, you may reuse numbers.

Part 2 . The Miller Integrator below has R1=1kohm and C1=10uF, and starts at t=0 with vI(0)=vO(0)=0. A voltage ramp is applied between t=0 and t=1ms, such that vi(t)=2000t, where t is the time in seconds, and after 1ms the ramp reaches a voltage of 2V. (The ramp rate is 2V/ms). The ramp waveform is illustrated on the left. (Note: the ramp is only applied for 1ms). Answer the following questions.  Match with closest answer, you may reuse numbers.  

Part 3 . You are given the following diode circuit. Please answer the following questions and show your work on the scratch paper.  R2 = 4kohms, R1 = 2kohms Match with closest answer, you may reuse numbers.

I understand that failure to keep my eyes consistently ahead will result in either a 50% reduction or a zero on the exam at the instructor’s discretion.   I also understand that I may not wear caps, hoodies, or other items which shield my eyes from the webcam, nor may I use ear buds while testing.
